Question

find the sum of

-5/7 + 3/-4 + 2/3

​

Answer 1

$\frac{-5}{7}+ (\frac{-3}{4})+ \frac{2}{3}$  {We can take the negative sign of 4 on the numerator}

LCM = 84

$\frac{-5*12}{7*12} = \frac{-60}{84} \\\\\frac{-3*21}{4*21} = \frac{-63}{84} \\\\\frac{2*28}{3*28} = \frac{56}{84}$

Now add: $\frac{-60-63+56}{84}$ = $\frac{-67}{84}$

So the answer is -67/84.
